What is a naturally occurring, inorganic solid that has a definite crystalline structure and chemical composition?
compound
crystal
mineral

Petrology
Igneous rock is divided into two groups, extrusive and intrusive. Extrusive igneous rocks form when magma makes its way to its surface as lava and the cools forming rocks. Which of the following will be the characteristics of the crystals?
Crystals are coarse-grained.
Crystals are very large.
Crystals are fine-grained.
Crystals are phaneritic
Which of the following represents the correct order of the processes responsible for the formation of sedimentary rocks?
Erosion, weathering, compaction, cementation, deposition
Compaction, cementation, deposition, weathering, erosion
Deposition, cementation, compaction, erosion, weathering
Weathering, erosion, deposition, compaction, cementation
What is the type of rock formed from lava that cools quickly that results to finer grain and smaller size of crystals?
Extrusive igneous rock
Sedimentary rock
Intrusive igneous rock
Metamorphic rock
What type of weathering is exhibited when the rocks are fractured, cracked, and broken down into small pieces?
chemical weathering
physical weathering
oxidation
pressure change
Which of the following cannot be considered as a role of gravity in erosion?
It moves glaciers down slope.
It loosens the land materials.
In mountains, it moves down large slabs of rocks.
It acts as agents of mass wasting like landslides, fall, mudflows, and avalanches.
Weathering involves physical, chemical, and biological processes acting separately or, more often, together to achieve the disintegration and decay of rock material. Physical weathering causes the disintegration of rock by mechanical processes and therefore depends on the application of force. What type of mechanical weathering occurs when freezing of water and repeated thawing in cracks of rocks?
abrasion
frost wedging
oxidation
solution
What term should be used to describe a semi-liquid hot molten rock located beneath the Earth?
Lava
magma
rocks
sand
What are the main factors for contact metamorphism to occur?
air and water
temperature and water
heat and reactive fluid
pressure and temperature
How do temperature and pressure affect metamorphism?
Pressure and temperature increase as you go up to the crust.
The deeper the rock depth, the higher the pressure and temperature.
Foliation happens as there is an increase in the pressure and temperature.
Magma cannot bake the surrounding rocks due to the difference in temperature.
Samer is walking down the river when she sees an unknown metamorphic rock. Which of the following characteristic can BEST help her to immediately identify the type of metamorphism that the rock underwent using a magnifying glass?

pressure
Which of the following words is NOT associated with metamorphism?
